10% of the Xbox One’s memory was reserved for Kinect functionality. Now that the console is being offered without a Kinect, that memory can be reclaimed and used for graphics processing. However, this does not mean that the Xbox won’t be able to make use of Kinect functionality it usually could. Eurogamer got the scoop from Microsoft’s Ken Lobb.
“Lots of people ask, ‘so, you’re taking back the GPU reserve for Kinect. Well, does that mean I can’t say, ‘Xbox, record that?’ No. You can always say that,” Lobb said. “So if someone says, ‘Xbox record that,’ it will work on 100 percent of the games, if you have a Kinect.”
Lobb described the new system architecture as being more flexible, allowing RAM and GPU to “bounce” to where it is needed. “It’s not like you have more RAM” Lobb said, “”You have more GPU, so go ahead and use it how you want,” Lobb said. “It’s more GPU plus more bandwidth to the GPU, so they both matter. So for some games it might be resolution, it might be frame-rate, or it might be, let’s throw in more enemies.”
